More than a hundred people are expected to join in the annual Big Sleep Out in Bristol tonight as part of Homelessness Awareness Week.
They'll be spending the night in the grounds of a church to raise funds and highlight the work being done by charities and organisations.
Homelessness Awareness Week begins in Bristol today.
In the last year, 5,000 households in the city were made homeless or were threatened with homelessness.
Bristol City Council says the problem is largely due to private sector tenancies ending.
The week will culminate in a sponsored 'sleep out' in the city on Friday.
Emergency accommodation for rough sleepers will be provided over the next few nights as freezing temperatures hit North Devon.
North Devon Council and Torridge District Council will help to provide the service at the Freedom Centre in Barnstaple, which offers shelter to individuals if the temperature drops below zero for three consecutive nights.
